SEBASTIAN ZIANI DE FERRANTI, OF GRINDL-EFORD, NEAR SHEFFIELD, ENGLAND.

APPARATUS FOR SPINNING, DOUBIIING, AND LIKE OPERATIONS.

T 0 all whom itmay concern:

Be it known that I, SEBASTIAN ZIANI DE FERRANTI, a subject of the King of Great Britain and Ireland, and residing at Grindleford, near Sheffield, in the county of Derby, England, have invented certain new and useful Improvements in Apparatus for Spinning, Doubling, and Like (Jperations, of which the following is a specification.

My invention relates to improvements in methods of and apparatus for doubling, spinning and like operations, and has for its object to enable higher rates of production and better work to be obtained than 1s possible with present machinery.

The present invention relates particularly to machines in which are employed spinning, twisting or doubling units each having a leading and a lagging part with independent drives of the leadlng or lagging parts, or

both.

Referring now to the accompanying drawings, which form part of the spec1ficat-1on:-

Figure 1 shows an end elevation partly in section of a form of spinning machine taken as a whole. In this figure for the purpose of simplification of the drawings, I have shown in the left hand side a doubling unit in which the inner part, 2'. 0., the spindle o-r bobbin carrier lags, and the outer part leads, while in the right hand side I have shown a doubling unit in which the inner part, 2'. 6., spindle or bobbin carrier, leads, and the outer part lags. Figs. 2 and 3 show sectional elevations of an arrangement for hydraulically retarding an unwinding bobbin. Fig. a shows a plan of same. Fig. 5 shows a plan of an arrangement of hydraulically retarding bobbins in staggered position for doubling.

I wish it to be understood that the draw ings are of a diagrammatic nature merely, and are not to be taken as working drawings.

Where desirable, the same reference characters are used to denote similar parts in the different figures.

In carrying my invention into effect, according to one form, as applied in a spin ning or doubling machine, in which air is the motive power, I construct the machine (see Fig. l) with a large horizontal air supply pipe, a, carried by a suitable frame on each side of which are arranged the stationary parts, 6, of the air bearing of each of the units of the machine. The figure thus Specification of Letters Patent.

or bobbin carriers being arranged at a convenient height for manipulation. In some cases the bobbins, It, may be omitted, and the material wound directly on the rotating part itself provided the same is suitably shaped.

For the purpose of driving the feed or feed and draw rolls as the case may be, I provide a gear wheel 2' on the bottom of the spindle which transmits power through an other gear wheel, 70, to a vertical shaft, m, running at a correspondingly lower rate. This shaft may be square in cross-section and slide telescopically in a hollow shaft, 17., coaxial with and driven by it, this hollow shaft having mounted on it one of the feed or drawing rolls, 0, which are disposed on a part of the machine above the corresponding spindle. The telescopic connection described serves to allow for the rising and falling of the rail, 6, carrying the spindles.

Suitable means are provided for giving a traverse motion to the rails, in order to allow the material to be laid evenly on the bobbins. According to the form shown in Fig. 1, a heart shaped cam, r, is fixed on the shaft, 8, which is driven for instance by a separate motor of any suitable type, since the speed of the shaft does not need to bear any definite fixed relation to that of the spindle. The cam, r, in contact with the roller or bowl serves to rock a lever, 25, pivoted at u, by way of the link, 22, the necessary constraint being given to the motion of the bowl by means of the second link, to, pivoted at 00, to the frame of the machine. The rails, e, carrying the spindles are connected respectively one at each end of the rocking lever, t, by way of the adjusting link, 2. It will thus be seen that a continuous revolution of the shaft, 8, causes an up and down motion to be transmitted to the spindles.

The feed rolls, 0, draw from one or more for the correspondingly opposite pairs of leading and lagging parts. The material to be operated upon thus passes from the bobbin, 2, around guides, down throughaguide eye, 30, between the feed rolls, 0, and thence over another guide, 5, to the rapidly rotating ring fliers carried on the stationary parts, 6, and thence through the bobbins, h, which as before stated are on the right hand side of the figure shown as leading parts and on the left hand side shown as lagging parts.

It will be understood that by suitably shaping the stationary part of the bearing the proper conduits can be obtained connecting with the central air pipe without any complication of connecting pipes. It will be understood also that the air bearing might be reversed, if desired, and the ring made to rotate inside the stationary part, but I prefer the external ring.

In some cases in addition to having a motor on the leading part, 6. 9., on the air borne flier or spinning ring, 0, in the particular example described, with reference to the left hand side of Fig. l, I may construct the lagging part as shown with a motor, d, for the purpose of assisting this lagging part when spinning fine counts. The arrangement I prefer is an air borne flier as the lagging part, which for fine work may be motor assisted so as to diminish the drag; for ordinary doubling, however, and the heavier kinds of work, the motor is preferably omitted.

With reference to the feed of the material according to my present invention, I drive the feed rolls from either, (a) the lagging part, (b) a lagging part internally disposed in relation to the leading parts, (0) the leading parts. In the machine above dealt with, I have shown and described gearing between the spindle and the shaft, m, through which motion is transmitted to the feed rolls, 0, disposed above. On the left hand side of Fig. 1, I have shown an internally disposed lagging part driving the feed rolls. On the right hand side of the same figure I have shown an internally disposed leading part driving the feed rolls.

Both of the above arrangements may be embodied in one machine as shown, or if desired a whole machine may be constructed with leading and lagging parts forming one of the arrangement above described. I however, prefer the form above indicated, in which the feed or feed and draw rolls are driven from the lagging part, as this is itself only driven through the material, so that when the material breaks, the lagging part stops and consequently the corresponding feed or feed and draw rolls also stop. It will be understood that when the lagging part is motor assisted, the feed orfee'd and draw rolls will not stop on the breakage of the material, but will slow down only. In this case, and also when I drive the feed or feed the draw rolls from the leading part, I may employ any well known automatic stop device, either to remove one of the elements of the friction drive or apply a brake, thus effecting the stop required. It will be understood that when I use the form of feed drives, (a) and (b), above indicated, abrake may be preferably applied to secure quicker stopping of the lagging part.

A method of hydraulically retarding unwinding bobbins is shown in Figs. 2,3and 4. Bobbins, 2, have retarders, 17, rigidly attached to their spindles, 18. The upper ends of the spindles are pivoted'on hinged arms, 19, the lower ends being mounted in suitable footstep bearings, 20, inserted in the bottom of the trough, 3. The amount of retardation may be varied by altering the level of the water in the trough, thereby varying the immersed area of the retarder, 17. Fig. 5 shows a modified arrangement which is preferably employed in doubling. In this arrangement the bobbins, 2, are staggered, so that the material may be unwound from adjacent bobbins and consequently disposing of the intermediate process of winding.

As described in my specification No. 930,848, the units of a machine to which my present invention is applied can be slowed down for convenience in piecing and handling. I have in this specification frequently used the term air borne, and use it in the sense that the bearing is air lubricated, and not in the limited sense that the weight of the rotating part is necessarily air supported.
